Question

I’m using Spring 2.5 for dependency injection management. I have a few classes that need to have some action triggered in the background when certain methods are called. I figured that the easiest way to do this would be with an annotation, like:

class MyClass {
  //...
  @DoSomethingElseInTheBackground
  function void doSomething() {
  //...
  }
  //...
}

I’ve written a BeanPostProcessor before and that was quite simple. So is there a way to do what I’m looking for? I’m inspired, in part, by @Transational.

Answer 1

You are correctly inspired by @Transactional. It uses Spring AOP, built-in feature of Spring framework.

Have a look at: @AspectJ examples with pointcuts based on annotations which describes the exact same use case.
